This commit prepares for when cacher tests are moved here
from the `tests` package. Tests in that package redeclare
some of the testing utils that exist here, so dedup-ing them.
This commit also adapts to any changes in test util signatures.
There are still some utils that can be reused but currently are
highly specific to some tests. (ex: watch_cache_test.go)
